Question 1.
Deb eats $$\frac{1}{2}$$ of her pear. John’s pear is cut into sixths. How many pieces must John eat to equal the amount that Debate?
Answer:
Given,
Deb eats $$\frac{1}{2}$$ of her pear.
John’s pear is cut into sixths.
$$\frac{1}{2}$$ × 6 = 3
John must eat 3 pieces

Question 2.
Josh and Jennifer are writing poems that are the same length. Josh has written $$\frac{2}{8}$$ of his poem. Jennifer has written $$\frac{2}{3}$$ of her poem. Who has written more? Explain using the fractions and <, >, or = in your answer.
Answer:
Given,
Josh and Jennifer are writing poems that are the same length.
Josh has written $$\frac{2}{8}$$ of his poem.
Jennifer has written $$\frac{2}{3}$$ of her poem
The numerator of both the fractions are the same but the denominators are different.
LCM of 3 and 8 is 24.
$$\frac{2}{8}$$ × $$\frac{3}{3}$$ = $$\frac{6}{24}$$
$$\frac{2}{3}$$ × $$\frac{8}{8}$$ = $$\frac{16}{24}$$
$$\frac{6}{24}$$ < $$\frac{16}{24}$$
That means Jennifer written more than Josh.
